Metallic nanoparticles are widely used due to their superior electrical, antimicrobial, and electromagnetic shielding characteristics. In this work, the surface functionalization of polypropylene (PP) fibers using magnetron sputtering with pure Cu and Ag targets in the presence of Ar gas was systematically investigated, in detail, in terms of surface morphology, tensile, abrasion resistance, moisture regain, antibacterial, and electrostatic properties. The results indicated that the nanocomposite films deposited on the PP surface were even and dense under proper treatment conditions. Compared with pristine fiber, breaking tenacity, abrasion resistance, and antibacterial properties of the Cu/Ag-deposited PP fibers were significantly improved, whereas the extension at break and moisture regain decreased in different degrees. Also, the electrostatic property of treated PP fabrics was studied. This work reveals that surface functionalization of Cu/Ag-deposited PP fiber is versatile, and the surface treatment that uses metallic nanoparticles by magnetron sputtering is a promising approach for achieving multifunctional textiles. Graphical abstract The Cu/Ag nanostructured film that follows Volmer–Weber growth pattern was successfully deposited onto PP fiber surface using the magnetron sputtering technique.

磁控溅射纳米结构沉积铜/银的聚丙烯纤维的表面功能化

金属纳米颗粒由于其优越的电，抗微生物和电磁屏蔽特性而被广泛使用。在这项工作中，系统地研究了在氩气存在下使用具有纯铜和银靶材的磁控溅射对聚丙烯（PP）纤维进行的表面功能化，详细研究了表面形态，拉伸强度，耐磨性，回潮率，抗菌性，以及静电性能。结果表明，在适当的处理条件下，沉积在PP表面的纳米复合膜均匀且致密。与原始纤维相比，Cu / Ag沉积的PP纤维的断裂强度，耐磨性和抗菌性能得到显着改善，而断裂伸长率和回潮率则不同程度地降低。还，研究了经处理的PP织物的静电性能。这项工作表明，Cu / Ag沉积的PP纤维的表面功能化是多用途的，通过磁控溅射使用金属纳米颗粒进行表面处理是实现多功能纺织品的一种有前途的方法。图形摘要使用磁控溅射技术将遵循Volmer–Weber生长模式的Cu / Ag纳米结构膜成功地沉积到PP纤维表面上。
